You are Chief Metacomet of the Wampanoag. The colonies are expanding into your lands and claim it is theirs.
The expansion is going to create friction and looks like war is imminent. The treaty also is one sided where you and the other tribes need to forego your guns. They have executed your people who are not bound to the law of the colonists.
Plan a strategy when to declare war on the colonist. This is important for you. Meet the Chiefs and persuade them to declare war on the colonist. They wont if they are not ready.
The colonist will declare war on you and the tribes if you and the other tribes have too many warriors.
Good luck.
